Features:
◇ Eachstandard module contains four-way separate reverse return optical receivingchannel, and mixed into two-way RF output, which can be composed of four-wayseparate receiver or two pairs of mutual backup receiver for the subscriber toselect.
◇ Opticallink loss automatic compensation or output level manual control can beoptional, optical input power changes 15dB, RF output level unchanged.
◇ Four-wayoptical signal receiving power status separately adopts tricolor LED auxiliaryinstruction.
◇ 30dBoutput level manual adjusting range.
◇ Plug-intype module design, small and compact appearance, flexible and convenientloading and unloading.
◇ Theunit chassis duct type design improves the unit’s reliability greatly.
